植物形态生长对策研究进展

植物在其生长发育的各个阶段的生长行为及生活史策略皆与植物的形态可塑性有很大关系,可在一定程度上决定植物物种在生境中的分布格局及种群行为.植物生活史对策是植物物种维持生长和繁殖的资源最佳分配方式,物种的适应性是物种在进化过程中累积起来的,在形态上有很明显的表现,植物采取不同的形态生长策略就是为了使物种在某些阶段达到最大的适合度.已有的植物形态生长对策研究主要集中在植物繁殖体形态、幼苗形态策略、生长可塑性以及繁殖策略等方面,植物各阶段形态生长策略的权衡以及与植物在群落中的分布关系被认为是今后该方面研究的重要方面.

Advances in Plant Morphological Growth Strategy

The plant life-history strategies of growth behavior in different phases of plant growth had a great relationship with the plant morphological plasticity, which could decide the distribution pattern of the species and population behavior under living conditions in a certain extent. The plant life-history strategies were the optimal resource allocation patterns for maintaining the growth and reproduction. The adaptability of species was cumulated during the course of evolution, which had a significant exhibition at the plant morphology. The plant had obtained the greatest fitness by adopting the different morphological growth strategies. The current studies of the plant morphological growth strategy focused on plant seed morphology, seedling morphological strategy, growth performance and plasticity and reproductive strategy etc. The trade-off of morphological-growth strategy during the different growing stages for plant and the relationships between plant morphological-growth strategy and plant distribution in community are the important study aspects in future.
